Default 4.9 conversion to 5.0

My truck has the 4.9 and i just don't think it's going to cut it! If i swap to a 302 how extensive will i have to get with the motor mounts?

Most importantly you will also need frame mounts for a v8, the -6 mounts directly to the x-member.

frame mount bolt in and are for the V8 motor mounts to sit on...

you'll need to find a donor truck and rob them to get them...

If your going to do the swap I would probablly just go to a 351 while your at it. Not going to notice a heck of a lot going from a 4.9 to a 5.0

whats up with 4.9 is it lagging or just not what you want....ive owned 3 in my lifetime and been some tuff as- motors .. its a 300 cubic inch motor with more torque then 5.0 302 if you truely want to change it go craigslist and look for a cheap truck and go from there

Before you bother swapping over the motors, you really need to look at what you use the truck for. The 4.9L is a hoss of a motor. I love mine for rock crawling, and a enough torque to pull over a house. Its just not a go fast for cheap motor.

Definately wouldnt bother with a 302. the 351 will be a little harder to find but would be worth the extra 49 cubes. Just make sure to get all the parts you will need off a donor vehicle and if you can have complete donor vehicle that would be better. Tranny bolts right up. Small block conversion is alot easier than bigblock.
